If the fediverse is to be adopted by the masses, the onboarding experience needs to change. A new user can’t be presented with a choice of instances as part of signing up or at least the process of making the choice needs to dumbed down a lot. I don’t know how or if this can be solved, I just know as someone involved in app development and UX that the current experience won’t work.
My mother would not know how to handle this paragraph: “Lemmy.world is one node in a network of hundreds of Lemmy instances. Before you sign up here, take a moment to explore all the instances at https://lemmyverse.net. You may find an instance with a regional or topical emphasis that speaks to you! Don’t worry about being left out; Lemmy instances are interconnected so users from each instance can participate with communities on other instances.”
For mass adoption it needs to be so simple that even non-techie older people can get through it without feeling like they might be doing something wrong.
I think this should be baked into client apps.
The popular email analogy works here too. When you are setting up a new phone, you get a default email client app that offers you to log in or sign up to the default email service. And usually user can choose to log in with their service if choice, for which they have to sign up in advance outside the client app.
Having a default Fediverse client on new phones is not happening anytime soon, but if someone’s mother installs a client app from the store link sent to them by a family member, she can get similar default onboarding experience.
Default instance can be picked by geo location, or maybe the less used out of 3 most popular instances. Or even maybe an instance ran by the client app developers.
Voyager defaults to lemm.ee IIRC
